Review: Works as it should. - What I have learned. CrystalClear PondShock ball works as it should if your pond is a balanced ecosystem, if you're having algae problems it's not from this ball, it's because your pond is getting too much sun and/or you don't have enough plants to take care of your pond waste material, that's simple more plants less algae, less Sun less algae if you have a small pond and you can place some kind of shade over it you will have less algae but the more plants you have will compete with the algae and algae won't be able to form because your plants will be eating the waste product that feed it. So I highly recommend this ball it works perfect in the pond and it does not harm your fish or your plants. I have this ball for my pond on Subscribe and Save. So when I need it I have it.
Review: This sucks. They owe me fish - This is no good! I had an established 700 gallon pond that had been doing fine with the exception of a bit of algae. This bomb killed all my fish. Within a couple days. 10 4 inch goldfish, 1 6 inch koi, and 20 minnows.
